WebIn taxinine and derivatives I-IV, the 9- and lo-protons absorb at 5.69-597 and 5*92-&09 ppm, respectively, whereas in the 9,lsdiol (IX), these protons absorb at 4.20 and 490 ppm, the large upfield shift being due to hydrolysis of the acetate group ings. In each case, the allylic proton, Hi,, absorbs at lower field than H,, and the ... WebAlthough taxinine lacks the important biological activity associated with taxol, it shares many structural aspects with taxol and so represents a relevant preliminary target. The synthesis of taxinine will provide a standard by which to judge the success of the overall taxane synthesis strategy.
